HANGER FOR SLIDING DOORS.

SPECIFIGATION forming part of Letters Patent No. 438,325, dated October14, 1890.

Application filed February 3, 1890. Serial No. 338,959. (No model.)

To all whom 't may concern:

Be it known that I, ALBERT B. PULLMAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Hangers for Sliding Doors, ofwhich the following is a specification.

My invention relates to an improvement in door-hangers of the classemployed for carrying into effect the invention set forth in the patentto Benjamin J. Cloes, No. 285,575, dated September 25, 1883, and in mypending application for a patent for an improvement thereon, Serial No.275,230, filed May 26, 1888.

The nature of my improvements will be clearly understood from thefollowing description, reference being had to the 'accompanyingdrawings, in which- 4 Figure 1 is a front elevation of a car-doorprovided with my improved hanger; Fig. 2, afront view of one of thesocket portions of the hanger detached; Fig. 3, a section of the same,taken on the line 3 3 of Fig. 2 and viewed in the direction of thearrows; Fig. 4:, a perspeotive view of the portion, of the hanger which`oonstitutes the track for the balls; Fig. 5, aperspective view of theweatherguard employed on railway-cars in conjunction with door-hangersof the construction herein described, and Fig. 6 a vertical sectiontaken on the line 6 6 of Fig. 1 and viewed in the direction of thearrows.

A is the wall of a car, B the slidingdoor, and C-the track for theballs, which is secured to the wall of the car above the door. As tothese features the construction is substantially the same as that shownand described in my pending application aforesaid.

D D are two socket-plates secured to the upper end of the door towardopposite sides thereof. These socket-plates have their upper ends bentover in a short curve, as shown at 25, corresponding with the curve 3along the edge of the plate C, which latter constitutes the support andtrack for the balls, and when in place the curved portion t of eachsocket-plate D rests upon one of the balls r, which in turn aresupported by the curve s of the plate C. Each end of the curved portionst of the plates D is closed by a projection q, producing a socket in theupper part of each of the plates D, from which the ball cannot escape solong as the hanger is in' place. To secure each plate D firmly to theupper end of the door, it is provided with lugs p, which enter recessesformed in the door and through which stove-bolts 0 pass to the outsideof the door, where'they are secured by nuts in the usual way. Thetrack-plate C is secured to the wall of the car above the door bystove-bolts o'.

'In practice, when applied to freight car doors of the ordinary width,Imake the sock* ets in the upper ends of the plates D, preferably, thoughnot necessarily, about ten inches in length, so that the door shall havea free movement of about twenty inches before the balls bring up againstthe endsof the sockets and become bound against rolling. Thenceforwardthe balls are compelled to slide for the remainder of the distancetraversed by the door in the same direction, which is in accordance withthe invention claimed in my pending application, named above.

By forming the hanger with two socketplates of the proper length, asabove set forth, all the advantages of my said former invention aresecured, together with additional advantages. Thus, the socket-platesbeing comparatively small and both exactly alike, the difficulty ofmanufacturing the hanger is greatly lessencd. Moreove-,ny presentconstruction does away with all necessity for enploying differentpatterns, since the socketplates may simply be set at the distance apartthat the circunstanccs render necessary.

WVith ny present construction, when applied to freight-car doors, it isadvisable to provide a weather guard or shield secured to the top of thedoor and closing the open space left between the inner ends of theplates D above the door. The device which I enploy for this purpose isshown in perspective in Fig. 5 and in section inFig. 6. It consists of ametal plate E, which is secured upon the top of the door and is providedwith a vertical flange n at its rear edge of such length as to fitbetween the ends of the plates D and of such height as to overlap thecurve s at the lower end of the plate C, as shown in Fig. 6. I prefer tohave that portion of the plate E which lies upon the top of the doorextend IOO from side to sideof the latter, and it is desirable that itshall be set upona bevel, as show'n in Fig. 6, in order that it mayserve as a Water-shed.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a door-hanger, the combination, With the Wall 'of the structureand the door, of .the plate C, provided with the curve s at its lowerend and secured to the Wall above the door, balls 'r, traveling in thetrack formed by the curve s, and plates D D, secured to the upper end ofthe door-one toward each side thereof-=and provided with the curved topst, to a 2. In a sliding car-door hanger, the combination, with the'wallof the' car and sliding* door, of the track-plate C s, secured to thewall above the door, balls 7", traveling upon the track, socket-platesD, secured to the upper end of the door toward opposite sides thereofand resting upon the balls r, and the weather-guar comprising the plateE, secured upon the top of the door and having the flange n, projectingupward between the inner ends of the plates D, substantially asdescribed.

ALBERT B. PULLMAN.
